standard instrumentation JFET op-amps fo EEG?
Another inspiring Ted Talk
http://www.ted.com/talks/tan_le_a_headset_that_reads_your_brainwaves.html
has gotten me interested in tan_le's headset_that_reads_your_brainwaves. Unfortunately, at $500 it's about $500 too expensive for me at the moment.
This does not use paste or gel nor does it require abrading the skin. How the heck to they do that? The suggestion was JFET op-amps used as standard instrumentation amp, just configure the op-amp to have a very high impedance. I've heard of op amps but this is all greek to me. Anybody interested in figuring out the sensors for this?
The hard part is the algorithm that flattens out the folds of the cortex and maps them. But that's for later. There a bunch of papers at the Emotiv website, but they are little deep for me.

From the descriptions, the sensor reads activity in the front lobe. As I've had mine removed (something about not wanting to risk another homicidal episode), the sensing won't work for me. You might have better luck.

Anybody know what EEG sensors look like on the inside? Are those just conductive foam?
